CLEARING ATTACHMENT FOR FLOWS.

SPECIFICATION forming part of Letters Patent No. 387,962, dated August14, 1888.

Application fiicd February 3, 1888. Serial No. 262,949. (No model.)

To aZZ whom it may concern.-

Be it known that I, MELVIN BARKER SUT- LEY, a citizen of the UnitedStates, residing at Rockland, (formerly \Vit'herups) in the county ofVenango and State of Pennsylvania, have invented a new and usefulClearing Attachment for Plows, of which the following is aspecification.

The object of my invention is to provide improved means for the purposeof plowing down clover, weeds, &c., by cutting away such obstructions inadvance of the plow; and my improvement consists in an attachment to thebeam of a plow of peculiar construction, as hereinafter described, andpointed out in the claims.

In order that my invention maybe fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which--Figure 1 is a side elevation of my improved attachment. Fig. 2 is a planview of the same on the line as a Fig. i. Fig. 3 is a verticaltransverse section thereof on the line 3/ 3/, Fig. 1. Fig. 4 is aninside view of the lower end of the standard. Fig. 5 is a plan view ofthe same. Fig. 6 is a side view of the retainingplate. Fig. 7 is a planview of thesame. Fig. 8 is a side elevation showing my attachmentsecured to the beam of a plow. Fig. 9 is an elevation of the attachmentlooking toward the opposite side to that shown in Figs. 1 and S.

1 is the beam, 2 the standard, 3 the share, and 4 the handles, of a plowadapted to receive my attachment.

5 is a clamp, and 6 the clamp-plate by which the attachment can besecured at suitable height or in desired position, as shown in full anddotted lines in Figs. 8 and 9.

A is a standard for attachment to aplowbeam, directly in front of theplow and in line therewith, formed with a socket, a, having aforwardly-extending arm, A, formed with inner cutter-fingers, a, andouter guard-fingers, a a vertical cutter-recess, a, and a countercutter-recess, a and a rearwardly-extending arm, A having groove a Z isa bolt secured to the standard, and O is a wheel mounted on said boltand held in place by a nut, z. This wheel is formed with transverseperipheral ribs r and a web, c,hav

ing serpentine or cam groove S on its inner face. Secured to thestandard between it and the wheel by means of a pivotpin, X, is a lever,B, formed with a collar, 2), occupying and working in the socket a ofthe standard, and having a short arm, B, provided with awristpin, b,carrying a roller, It, working in the serpentine or cam groove.Suspended from the lever B by a link, I), is a cutter-bar, D, guided inthe counter-recess a and carrying knives or cutters d,working in thefront portion of the recess aflacross the fiugersn andn p are steelbearing plates or knives riveted or otherwise fastened to the fingers.The cutter-bar is retained in place by means of a v plate, at, securedby its rib m in the recess a by bolts m and nuts in. To the upperguardfinger is secured by bolts a and nuts n a guardextension, n.

F is a sweep-bar secured by a bolt, f, and a nut, f, in the recess a ofthe rear arm, A.

The wheel 0 runs on the ground, and the roller R, following thecam-groove thereof, causes the lever Bto oscillate on its pivot andimpart a vertical reciprocating movement to the cutter-bar D, which cutsthe grass or weeds, after the manner of a mowing-machine, allowingthereby the plow to have a free passage through such entanglements. Thecut weeds and grass are swept over or downward into the preceding furrowby the sweep-rod F.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent.

1. In aplow attachment, the combination of the standard having a.forwardly-extending arm provided with fingers, the lever pivoted to thestandard having a wrist-pin, the wheel having a cam-groove in which thewrist-pin works to vibrate the lever, and a cutter-bar suspended fromthelever,having knives working against the fingers, substantially asdescribed.

2. The combination, with the plow and beam, of the standard havingfingers, the lever pivoted to the standard having a wristpin, acutter-bar suspended on the lever, having knives working over thefingers, and a wheel journaled to the standard,havingacamgroove in whichthe wrist-pin works to vibrate the lever, substantially as described.

3. In a plow attachment, the combination ICO of the standard having aforwardly-extending arm provided with fingers and formed with acutter-recess, the lever pivoted to the standard having a wrist-pin, thewheel having a camgroove in which the wristpin works to vibrate thelever, a cutter-bar suspended from the lever, having knives, and theretainingplate, substantially as described.

4. In a plow attachment, the combination of the standard having aforwardly extending arm provided with fingers and formed with acutter-recess, the lever pivoted to the standard, having a wrist-pin,the wheel having a cam-groove in which the wrist-pin works to vibratethe lever, a cutter-bar suspended from the lever, having knives, thebearingplate, and the retaining-plate, substantially as described.

5. The combination of the standard having a socket and fingers, acutter-bar having knives, a lever on which the cutter-bar issuspended,having a collar occupying the socket, a pivot-pin by which thelever is hinged to the standard, and a wheel, by which the lever isoperated to reciprocate the cutter-bar, substantially as described.

6. In a plow attachment, the combination of the standard, a sweepsecured to the standard, and a carrying-wheel supporting the attachmentand sweep at the proper height,substantially as described.

7. The combination of the standard having forwardly-extending arm formedwith fingers, guard-extension secured to the upper finger, cutter-bar,lever, wheel, and mechanism by which the wheel is caused to operate thelever, substantially as described.

8. The combination of the standard having fingers, the cutter-bar, thelever pivoted to the standard, the link by which the cutter-bar issuspended on the lever, a wheel having a continuous serpentine groove,and a wrist-pin by which the lever 'is connected with the camgroove,substantially as described.
